Poncho pretty well summed it up. as far as there being no plane that hit the Pentagon, those "ideas" are based on vague and misleading edited clip and snippets from reports given by people on the ground. Here is an example:
There were other conflicting eye witness accounts as well. The MSM doesn't seem as if it is to interested in airing these accounts for some reason or other.
Anyone looking into "both sides" of the story is going to be hard pressed to find the "other side" presented fairly by the so called credible news agencies and their corporate talking heads. Such as Glenn Beck who attempts here to "funnel" his readers into the old "ice cream close". "Which do you prefer chocolate or vanilla"? Which do you prefer "Coincidence or Conspiracy?"
